Using ventus 532 for RICS of Gold Nanoparticles
In a paper by Nieves et al. titled “Photothermal Raster Image Correlation Spectroscopy of Gold Nanoparticles in Solution and on Live Cells” (published by Royal Society Publishing), the ventus 532 is used as the excitation laser within the photothermal confocal microscope set-up. In the experiment, the Raster Image Correlation Spectroscopy (RICS) technique enables observation of a greater area of a biological system through measuring the diffusion of fluorescently labelled molecules from stacks of confocal microscopy images. Utilising gold nanoparticles prevents photobleaching, so that cells can be viewed for a longer time period.
